My view is that this can work in bare-bottom tanks but should not be attempted otherwise. The substrate should naturally collect organic waste which the various bacteria [and we are talking bacteria other than the nitrifying species here] can break down. This is explained in more detail here:http://www.tropicalfishkeeping.com/f...quarium-74891/
This allows for a natural biologically-balanced aquarium.

Another problem with a filter flow that is strong enough to achieve what you suggest is that this is not tolerable by most fish, at least not on a long-term basis.
